I too love the SVG Path Editor, used it many times to create SVGs that had "nice code". Nobody really appreciates it, but it just felt good.
Inkscape on the other hand almost inevitably creates really messy SVGs with a lot of transforms (why??) that make it almost impossible to see actual coordinates.
But as I said, nobody cares about how clean and nice your SVG paths are and I don't either most of the time, so I'm still a regular user of Inkscape. Thanks to the team :)
There are options to simplify and optimize SVGs on 'Save as'. Apart from the Plain SVG, there is Optimised SVG that you might find useful since you're into editing manually.
